This has been done before, but I added the twist that the Joker's plans to kill the Batman are never, ever simple. One does not SIMPLY kill the Batman... One goes about it in a very convoluted, unnecessarily complex way.

Funny that, see right at the end of the ep/chap, Joker decides to just shoot Batman, and Batman (unexpectedly!) escapes. I think Joker has no original material. He steals from Harley.

Not some half baked TV show!Harley: Maybe you should kill em by baking em into a giant cake!Joker: No, that's terrible...But wait! What if I killed them by baking them into a giant cake!Harley: Puddin, that's my-Joker: Quiet, Harley! I'm creating art, here!
